Incorrect access control in the getWiFiIpMacTable function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain Wi-Fi client MAC-to-IP mappings via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated information disclosure in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 exposes the internal Wi-Fi client MAC-to-IP mapping table to any attacker with adjacent network access. The getWiFiIpMacTable function in the router's CGI handler fails to enforce authentication, allowing a crafted POST request to /cgi-bin/cstecgi.cgi to return a full enumeration of connected wireless clients. …

Vulnerability AssessmentAI
| Exploitation | Attacker must be within adjacent network range - either connected to the same Wi-Fi network as the T6, or on the same LAN segment (AV:A). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate-to-low despite the access-control bypass classification. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Check the TOTOLINK firmware download page (https://www.totolink.net/home/menu/detail/menu_listtpl/download/id/190/ids/36.html) for a patched firmware release and apply it immediately if available - no vendor-confirmed patched version number is present in available data at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
